I have a pair of the (slightly) older proline 750's. Is the consensus that the pro 900 is a bit less forward once burned in? For me the 750 is just brilliant on some recordings, and fatiguing via both too much treble and too much bass on others. I was hoping for a closed can that was not quite as bright and fatiguing as my not so dearly departed grados, and just a bit more forward and efficient than my beloved but currently under-amped by my Pico Sennheiser 580's.
Is the 900 a more "pleasant" headphone to listen to?
Is the bass as present as on the 750? (not necessarily a plus for me)
Do any of you find it fatiguing via too much bass or treble?
Is it any more comfortable than the 750? (750's not bad, but a bit heavy)
The 750 is an OK fit for my needs. I'm trying to decide whether the 900 would be a better fit, or if I should move to other brands.
Again, Here's sort of what I'm looking for: CLOSED with a sound signature similar to my Senn 580's, but a little less laid back, and more efficient for being driven with my Pico, or straight out of the iPod / iPhone once in a while. I love my shure 530's, and would love to capture that sound in a CLOSED can at $250 or less, new or used.
What I'd like to change on my 750's:
Tighten the base, or lessen it just a bit. At times it is sublime, at times it is just fatiguing. This could be the quantity available in the 750, or the quality and content of the recording itself, I'm not sure. My senns rarely, if ever have this issue, same for the shures.
Slightly more rolled off highs, or slightly more present mids
A bit more "lushness"
I don't know if it's the S-logic, or just me and closed cans, but I swear after a while, I get almost a tremelo effect and have to pull them off and rest my ears. 1.5 - 2 hours seems to be my wear limit, though this is the case with most cans, so this is not a major complaint. I would like a pair I can wear for 3 or 4 hours though.
Lastly, (trans)portability - the ultrasone form factor with folding and especially rotating the cups so the whole package folds flat is perfect. This foldability, at least the cups rotating to fold flat is a necessity for my needs from "this pair" of cans.
Oh, and I find the blue color borders on ugly so a different color would be nice. Not that I'm vain or anything...
